What should drivers do when pedestrians are crossing at a traffic light and they are turning right?

When drivers are turning right at a traffic light where pedestrians are crossing, they must prioritize pedestrian safety. The appropriate action is to wait until pedestrians have completely crossed the driver's lane and at least half of the adjacent lane. This ensures that pedestrians have enough time and space to cross safely, reducing the risk of accidents.

Choosing this approach emphasizes the importance of being cautious and observant of pedestrians' rights to cross, especially in busy urban environments. It also reflects traffic laws that require drivers to yield the right-of-way to pedestrians. Being patient and allowing pedestrians to clear the crossing not only helps prevent potential collisions but also fosters a safer environment for all road users.

Other options, like alerting pedestrians with a horn or proceeding if the light is not red, do not adequately ensure the safety of pedestrians. Therefore, waiting until the crossing is completely clear is the best and safest course of action.
